This paper takes soil crack quads in Yuanmou arid-hot valley region as examples, selecting several morphological indicators, and analyzes the soil crack＇s morphological features under various development degrees. By statistic analysis, three quantitative indicators for surface morphology are selected, namely soil crack area density, area weighted mean fractal dimension and connectivity index R, which can not only express the development intensity of soil cracks, but also effectively describe its morphological complexity and connectivity. The research results set a good base for the establishment of soil crack assessment system in Yuanmou arid-hot valley region.展开更多

Media images of ideal bodies encompass judging gazes. These gazes affect and discipline people and may make it challenging for them to accept their bodies. The data material is part of the interdisciplinary Nordic project called “Beauty comes from within: looking good as a challenge in health promotion”. Based on 20 interviews with Norwegian men and women, of whom 10 have particular appearance-related problems, the article discusses the relationship between the media-depicted body ideals, descriptions by informants of what a good-looking body is, body satisfaction and body practices. The article shows resonance between how people describe good-looking bodies and satisfaction or not with own bodies. Women express more dissatisfaction with their bodies than men, but the article shows that many have strategies for trying to accept their bodies as they are. The comparative perspective highlight that the people having deviant bodies, more than those with normal bodies, balance the idea of “being myself” with the idea of “doing the best out of my (bodily) situation”. Most interestingly, they show that it is harder to accept handicaps that are changeable, like overweight, than harelips, deformed legs and skin injuries. As such, overweight becomes a double burden.展开更多
